SAW-TAB.

SPECIFICATION formingpart of Letters Patent No. 288,867, dated November 20, 1883. Application filed May 21,1883. (Model) To all whom it may concern Be it known that we, JOHN D. RYAN and PAUL LAUE, of East Saginaw, in the county of Saginaw and State of Michigan, have invented a new and Improved Saw-Tab, of which the following is a full, clear, and exact description.

-Our invention relates to the tabs that are applied to gang and other saws for connection of the buckles used in stretching the saws, and which are always riveted to the saw-plates at an expense of time and labor.

The invention consists in a two-part tab, one portion having lugsor feathers that pass through slots or openings in the saw-plate, as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a face view of a portion of a saw with our improved tab. Fig. 2is a crosssection on line a: w of Fig. 1. Fig. 3 shows the end of the saw-plate with the tab removed. Fig. at shows the two portions of the tab separated. Fig. 5 is an end view of the same.

A is the saw-plate, and B B the two plates forming the tab. ,One plate, B, as shown, is formed with lugs or feathers a, preferably three in number, that pass through slots or openings bin saw-plate A. The outer faces of lugs a. are wider than the slots 6, and the edges of the lugs and their plate B are under cut or recessed, so that their edges lap over 5 the edges of the slot, and thereby assist in holding the plate B, and also give a hold for the straining-buckle. The othertab-plate, B, is placed against the opposite face of the sawplate, and, a screw or rivet, 0, being put through the tab, is held securely without any "possibility of its shifting or being torn away by the strain. The plate B is preferably recessed, as shown, to fit the lugs a, so as to strengthen the parts.

This tab can be readily applied without the labor of applying three or more rivets, as usually required, and when in place the strain is not upon rivets, but upon the lugs, which have ample strength. It can also be removed easily without injury, while the riveted tabs are frequently broken by removal; and our tab being practically indestructible by ordinary use, the frequent expense of new tabs is saved. Thus, in the respects of utility, durability, and economy, our improved tab is greatly superior.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. A saw-tab consisting of two plates, one of which is provided with lugs for entering apertures of a saw, and between which plates the saw is to be secured, substantially as shown an (1 described.

2. The combination, with asaw having ap ertures b, of the plate B, provided with the lugs a, and the plate B, the said plates being placed on opposite sides of the saw and secured together by a screw, substantially as herein shown and described.

3. The combination, with asaw having apertures b, of the plate B, provided with the lugs 0:, having undercut edges, the plate B, and the screw 0, substantially as herein shown and described.
